Application tied September 5, 19M.

This invention relates to an improvement in condensers and more particularly to surface condensers adapted to be empio ed as fractionating or dephlegmating con ensers l in the refinement of petroleum roducts, al-

though as will be understood, t 1e invention is not limited to this particular purpose. Heretofore, in the refinement of petro cum and similar' products, vessels or similar devices entirely independent of a condenser have been employed for fractionating and dephlegmating purposes. The object of my resent invention is the provision of a conenser within which the fractionating or 16 dephlegmating action together with the usual condensing actions are combined in the same apparatus. For this purpose in carryin out the invention the` condenser which 1s a surface condenser is provided with means .for causin the condensable vapors to commin le wit the condensate in the condenser, an for this purpose a series or lurality of suitably placed fractionating or ephlegmating pans or equivalent devices are employed.

In carryin out the invention I also prefer to provi e means for withdrawing the condensate from any or all of the fractionating or dephlegmating pans or similar devices, and to furthermore employ suitable means for effecting a temperature control in the condenser or in any one of a series of condensers when a battery of the same is emplolyed.

he invention will be hereinafter more particularly described in conjunction with the accompanying drawings, in which Figure 1 is an elevation and partial central vertical section illustrating a condenser made in accordance therewith.

Fig. 2 is a plan illustrating a battery of condensers.

Fig. 3 is a sectional elevat-ion illustrating a manner of placing the fractionating or dephlegmating pans, and

Fig. 4 is a section on line 4 4, Fig. 3.

' In carrying out my present invention, the condenser employed is preferably of the tubular type and as will be understood, a cooling medium ma be caused to How through the tubes and t e condensable vapors admitted to the shell or body of the condenser so as to surround the tubes, or the circulatn or cooling medium may be vcaused to ow mm no. nam.

through the body or shell of the condenser and t e condensable vapors introduced into the tubes so as to be condensed therein. In illustrating the invention, the former type of apparatus is shown. 1t will furthermore be understood, that the condenser employed 1n carinng out the invention may be constructe to com rise a single pass, a double as s or any mn tiple of passes for the circuating or cooling medium, and also that the condenser unit embodying the invention may be employed in any desired or necessary numbers comprising a battery of units which constitute a single operating apparatus. As will be apparent and still furthermore understood, t e condensers may be arranged so that the tube elements are placed either horizontally or vertically, as occasion may require.

By reference to the drawings and particularly to Figs. 1 to 4 inclusive, it will be seen that in carrying out this invention each condenser unit com rises a body or shell 10. The form of con enser shown in Figs. 1 and 2 is that of the vertical type and beneath the shell 10 there is a box 11 for the circulating or cooling medium and this is mounted on a base plate or cover 12. The ends of the shell and also of the box for the circulating medium are suitably flanged and between the flange at the upper end of the box 11 and the lower end of t e shell 10, the usual tube plate 13 is placed. Fixed at corresponding ends in the tube late 13 are the tubes indicated at 14. At t leir upper ends these tubes are connected in heads indicated at 15 and 16, so that the condenser unit contains two sets of tubes each of the double pass type. At the upper end of the condenser unit there is a bonnet 17 enclosing the unit at the top thereof.

In a suitable position the condenser shell 1s rovided with a vapor inlet 18 and also wit a condensate outlet 19. In this instance the vapor inlet is at the upper end of the shell and the condensate outlet at or adjacent the lower end of the shell. Interiorly the 'shell is divided into compartments by a partition wall 20 which may be secured in position therein in any desired manner and preferably extends from the bonnet 17 at the upper endthereof to a point adjacent the lower end of the shell at the opposite end thereof. The box 11 for the circulating medium is provided with inlets 21 and 22 for the circulating medium and with outlets 23 and 24 for the circulating medium. In this type the condenser unit is preferably rectangular and the circulating medium inlets are placed at one side thereof, and the circulating medium outlets at the opposite side thereof. Extending through the box 11 for the circulating medium there is a division plate or partition wall l1. Also extending through the water box 11 and at right angles to the artition wall 1l is another partition Wal 112 which is necessary for properly directing the flow of the circu lating medium through the tubes of the apparatus. In the use of this condenser the circulating medium consequently enters one set of tubes by way of the inlet connection 21,' asses upwardly through the tubes a to the ead 15, downwardly through the tubes b to the outlet 23. Similarly a portion of the circulating medium passes through the other sets of tubes entering the box 11 by way of the inlet 22, passing upwardly through the tubes c to the head 16 and then downwardly through the tubes d to the out let connection 24.

As hereinbefore stated, condenser units may beremployed in batteries of any desired number. As illustrated in Fig. 2 in con'unction with the initial condenser unit as ereinbefore described there are shown four additional units associated therewith and des- 1 nated respectively at 25, 26, 27 and 28.

e circulatin medium to the initial unit and also the units 25 and 26 may be supplied through a manifold 29. Between the manifold 29 and the inlet connections to the respective units I employ sets of valves indicated for the units respectively at 30, 31 and 32. These valves as will be understood, may be manually operated or automatically operated by means of a suitable thermostatic device or otherwise, to regulate the flow of the circulating medium to and through the several condenser units and in this manner to effect a temperature control therein. Similarly the circulatin medium as the same passes from the con enser units may be carried away through a manifold 33. The manifold 33 is connected to the sets of outlets for the circulatin medium from the units of the apparatus y way of valves 34, 35 and 36 for the respective units. This type of apparatus is adapted for the utilization of the oil as a circulating medium in the initial and succeeding units 25 and 26. This as will be understood increases thetemperature of the oil when thus used as a circulating medium before the same is vaporized, thereby requiring less heat to vaporize the material which is being operated upon in the apparatus. In the final units of the battery, water or other liquid may be employed as the circulating medium and supplied .o the units by a manifold 37. This manifold 37 is connected to the respective inlets for the circulating medium by means of valves 38 and 39. These valves may be operated manually or automatically as hereinbefore stated, to elect a temperature control in each individual unit of the apparatus. The circulating medium as the same leaves the units 27 and 28 ma be conveyed away by a manifold 40. This manifold 4() is connected to the circulatin medium outlets of these units by valves indlcated at 41 and 42 for the respective condenser units. It will be understood of course, that the extent to which the outlet valves are open may be controlled automatically and that the positions of these valves are naturally dependent upon the positions of the valves at the circulating mc dium inlet side of the apparatus.

Interiorly the body of the condenser is provided with a plurality of fractionating or dephlegmating pans indicated at 43. These pans may be of any desired number or type and are placed in an suitable or necessary positions within the body of the condenser unit. Furthermore, they ma also be maintained in position in any esired manner. As shown in Fig. 1 of the drawing, however, each of these pans 43 is provided with an upturned rim 44 in order that each pan may receive and retain the predetermined part of the condensate, which after the pan becomes filled, overflows the rim and drips to the next succeedin pan in order that thereby the uncondense vapors may be caused to intimately commingle with this condensate as both the condensate and the condensable and noncondensable va ors pass through the apparatus. In this orm of apparatus the vapors as hereinbefore stated, are admitted through the inlet connection 18. They then ass downwardl through the outer section o the condenser ody around the sets of tubes a-b and under the lower end of the partition wall 20, and then u wardly around the tubes c-d, the non-condbnsable vapors and the condensable vapors still remaining uncondensed pass by Way of the outlet opening 18 to the next succeeding unit of the apparatus. It will be understood of course, that the condensate from each apparatus may be withdrawn in the customar or any suitable manner 4by way of the con ensate outlet 19.

The fractionating 'or dephlegmating pans or condensate receptacles as hereinbefore stated, may be formed and maintained in position in a suitable manner. As illustrated in Figs. 3 and 4, however, each of these pans 43 may be made of sheet metal and provided with a plurality of apertures corresponding in number and position with the tubes which are caused to pass through the pan. Each alperture as indicated at 45, as punched in t e pan is preferably of a smaller diameter than that of the tube which passes through the same, and in predetermined positions it is slotted radially as indicated at 46, so that when the tubes are forced through the apertures in the pan a flange 47 is turned upwardly to surround and engage the outer surface of each tube. Also as indicated in these figures, I may employ bolts 48 iixed in the tube plate in suitable positions and extending through apertures 49 provided therefor in the fractionatng or dephlegmating pans. Each of these bolts is fitted with spacer sleeves 50 and 51 extending between adjacent pans in order to support and maintain the saine positively in position.

Also as shown in Fig. 1, the shell 10 may be provided with a plurality otI outlet apertures 52 cach making connnunieation with one of the dephlegniating pans in order that when necessary or desirable any pan may be drained, it being understood that any suitable connection may be made with these drains for this purpose. It will also be apparent that the forms of the invention here- 1n shown and described are illustrative Y merely of apparatus that may be used in carryingout the invention, as other equivalent devices of apparatus may be used to equal advantage Without departing from the nature and spirit of the invention.

I claim as my invention:

1. In a surface condenser, a shell, a plurality of staggered pans within the condenser shell for receiving condensate and causing the same to intimately commingle with the vapors in the shell, a plurality of tubes passing through the said pans, and means for circulating a cooling medium through the said tubes.

2. In a surface condenser, a shell, a plurality of superimposed fractionating or dephlegniating pans staggered within the said shell for receiving and containing quantities ot condensate and from each ot' which the condensate flows to the next succeeding lower pan whereby the condensate is caused to intimately colnmingle with the vapors in the condenser shell, a plurality of tubes extend through the said pans, and means for circulating a cooling medium through the said tubes.
